Latest Patents

Biao Lu's latest patents include groundbreaking technologies for engineered exosomes. One patent details the use of engineered exosomes for the delivery of bioactive cargo utilizing transmembrane VSV-G. This invention demonstrates that VSV-G can effectively load protein cargo onto exosomes and enhance their delivery capabilities through a pseudotyping mechanism. The research shows successful targeting and incorporation of VSVG fusions into exosomes via gene transfection and fluorescence tracking. Notably, the pseudotyping process does not alter the size or distribution of the exosomes, and both full-length VSVG and VSVG without the ectodomain integrate into the exosomal membrane. This suggests that the ectodomain is not necessary for protein loading. Furthermore, exosomes pseudotyped with full-length VSVG are internalized by various recipient cell types more effectively than those loaded with VSVG lacking the ectodomain, highlighting the ectodomain's role in cell tropism. This invention provides a novel genetically encoded pseudotyping platform for loading and enhancing the intracellular delivery of therapeutic proteins through exosome-based vehicles.

Another patent focuses on engineered exosomes for the delivery of bioactive cargo using transmembrane tetraspanins. This technology incorporates a tetraspanin transmembrane anchoring scaffold onto the exosome membrane. The scaffold features multiple attachment sites, allowing for versatile loading of peptides in various forms or combinations. Tetraspanins naturally anchor to the exosome membrane, ensuring biocompatibility and robust delivery of bioactive cargos within mammalian systems.
